Do you have any thoughts on the fact that sukuna can use rct to heal others but Gojo can’t, in consideration to how they chose to live with unmatched strength? Or alternatively, do you think there was a further meaning to sukuna being one of the very few who can use rct like that, alongside shoko (the leading healer) and Yuta (patron guy of true mutual love) or is it simply because he’s the Best at sorcery? I can’t recall any moments he used it on others in the story rn, so what would be the purpose of having that trait there?
oh yeah I have so many thoughts, and this is a really interesting set of questions!!
first off, re: when sukuna used it in canon. To my memory, he only used it once! It was on Megumi during Shibuya, to keep him from dying while Sukuna killed Mahoraga. So the only use we have from him is, in itself, innately selfish. (also side tangent this is why I thought it was very funny to make him use it on Megumi again in Recurrence. We are always doomed to return very close to where we started).
So from a practical in-story perspective, I think it's because Sukuna can use it to keep people who are useful to him alive.
Now, for my own interpretation of it-- I think it speaks to the ethos sukugo has in how they approach a world that's fundamentally weaker than them. Gojo's inability to use RCT on other people speaks to the fact Gojo strongly believes he can't help people who haven't asked for his help. He waits for people to be ready to be saved, to want to save themselves! It fits him really well that he cannot force salvation on other people.
But Sukuna doesn't care about waiting for other people to be ready. He does as he pleases, and uses people as he pleases, so him being able to use RCT on others is, in a way, saying he doesn't have to care about their boundaries or their feelings. They will live and die at his whims.
There's another aspect of it I find really poetic too, that comes from my personal headcanon for Sukuna-- he was born with the pieces of someone meant to be honored as Gojo was, but that was twisted and warped at birth (or before birth), and the world scorned him for it (the disgraced one, the fallen one, etc). So imo, RCT is a piece of heavy irony. He could have been a savior. He could have been a healer! He is neither, and refuses to be.
